Allied Control Incorporated is a manufacturer of many varied types relays which can be defined as follows:

1. Clapper Relay - is one which has its armature pivoted or hinged to a fixed part of relay (usually the frame or heelpiece). They can be classified for general purpose industrial use.

Allied Control Types are BO, BOY, PB and PO.

2. Coaxial Relay- (antenna switching or RF switching) is one that has contacts that switch radio frequency currents with a minimum of losses. Current range 1 watt at 500 MHz.

Contact factory for information.

3. Crystal Can Relays - are those hermetically sealed in small sizes to meet stringent environmental conditions of temperature, shock, vibration and thermal shock. Allied Control Types are Crystal Can Relay - WKJ, Sensitive, full size - S,1/2 size.

5. Hermetically Sealed Relays - are those relays enclosed in metal housing with insulating header terminations. Before sealing, an inert gas such as nitrogen is put into the unit to prevent oxidation. Most Allied types can be hermetically sealed.

For technical information please contact factory.

6. Latching Relays (Magnetic) - are those that use a permanent magnet to hold in armature, after the coil power has been removed. To reset, energize other coil or same coil in opposite polarity.

Allied Control Types are T-351

7. MIL- Spec Relays- are those built to meet stringent performances and environmental characteristics that are spelled out for Military/Aerospace use. They are MIL-R-5757 and MIL-R-39016.

Allied Control Types are S, WKJ, WJJ and MH.

8. Power Relays - are those in the industrial - general-purpose types that have contacts rated from 5 to 15 amperes at 28VDC or 115/230VAC or higher. Allied Control Types are BO, BOY, PO, and PB.

For technical information please contact factory.

9. Low Level - are those relays whose contacts switch currents in "dry circuits" or low level loads, usually 100 millivolts or less and I milliampere or less. Most Allied Control relay types have low level switching capability.

10. Sensitive Relays- are those relays that require 100 milliwatts or less of coil power to operate.

Allied Control Types are SW, TS154, and WJS.

11. Telephone Relays- Usually applied to an armature relay with an end mounted coil, an "L" shaped heelpiece, and contact springs mounted parallel to the long axis of the relay coil.

Allied Control Types are T154, T163 and T351/T362.

12.Time Delay Relays (Electronic)- are those units that encompass an electromechanical relay with suitable network of circuitry to affect a given delay in time.

Allied Control Types are TD1O
